The Savanna-bush-woodland National Parks contain some of the greatest plains game concentrations in the world. The big-five: Elephant, Rhinoceros, Buffalo, Lion, and Leopard are manifestly plentiful in these parks. The mountain National Parks boast of some of the most superb mountain scenery in Africa, the snow capped peaks of Mt. Kenya with excellent climbing adventures and beautiful moorlands for mountain walkers.

Giant groundsels and lobelia are some of the eye-catching flora on Mt. Kenya and Mt. Elgon. In addition to the mountain scenery and flora, the mountain parks are homes for the big five (no lions in Mt. Elgon) and a host of other rare mountain species like Bongo, Giant Forest hog, melanistic cats and many mountain bird species.

The lake ecosystem national parks contain the greatest concentration of flamingo in the world (Lake Nakuru National Park) and the greatest crocodile colony in the world (Sibiloi National park). There are also myriads of other bird species in and around the lakes, schools of hippopotamus and hundreds of land mammals species on the shores of the lakes.
